Title: Linear amplifier control
Inventor: RIPSTRAND KRISTER INGEMAR
IPC: H03F1/32
Filed: 1994-01-28
Granted: 2003-04-01
Abstract: A method and apparatus for controlling a feed-forward compensated power amplifier system is disclosed which uses a spread spectrum technique to cover a control signal or signals and injects a composite signal at a suitable point into the feed-forward amplifier system to reduce distortion. The amount of bandwidth spread is governed by the amount of processing gain needed in the remapping process and the needed time response of the system. Control signals after remapping of the spread spectrum at the output of the system are correlated in a match filter correlator and the result is used to control, in either polar or Cartesian coordinates, the injection, in anti-phase, of the extracted distortion into the feed-forward amplifier output.
